A mosquito net for a hammock either wraps around the outside of your hammock like a cocoon or comes built into the hammock itself, creating a sealed mesh enclosure that keeps biting insects out while you sleep. Choosing the right one comes down to mesh density, entry style, how it attaches, and whether you need protection from the bottom as well as the top.
Integrated vs. Standalone Nets
Hammock mosquito nets come in two broad categories. Integrated bug nets are sewn directly into the hammock, forming a permanent mesh canopy over the sleeping area. They offer full coverage with minimal setup since the netting deploys automatically when you hang the hammock. The trade-off is weight: you carry the net every trip whether you need it or not, and if the mesh tears, repair is more involved.
Standalone nets are separate pieces of gear you drape over or suspend around your hammock. They’re more versatile because you can leave them home on cold-weather trips when bugs aren’t a concern, swap them between different hammocks, or upgrade your mesh without replacing the whole system. The downside is that a poorly fitted standalone net can leave gaps, especially along the bottom edges, that mosquitoes will find.
Mesh Density: The Number That Matters Most
Not all mosquito netting blocks the same insects. The key specification is holes per square inch, and the differences are dramatic.
- 156 to 200 holes per square inch: Standard mosquito netting. Stops mosquitoes but lets no-see-ums, midges, and sandflies pass straight through.
- Around 500 holes per square inch: Often marketed as “no-see-um proof,” but this is misleading. Sea to Summit’s own documentation acknowledges that 500-hole mesh does not actually stop no-see-ums or sandflies.
- 1,000 to 2,000 holes per square inch: Genuine no-see-um protection. This is the range that blocks mosquitoes, no-see-ums, midges, and sandflies.
If you’re camping in temperate forests where mosquitoes are the primary concern, standard netting works fine. If you’re heading to coastal areas, tropical regions, or anywhere with biting midges, look for mesh in the 1,000-plus range. Many products sit around 1,600 to 1,700 holes per square inch, which provides reliable protection across insect types. Finer mesh does reduce airflow slightly, so in hot, humid conditions you’ll want to balance bug protection against ventilation.
Entry Styles and How They Differ
How you get in and out of your hammock net matters more than it sounds. There are three common designs, each with real trade-offs.
A full-length side zipper runs vertically along one side of the net. It’s intuitive to use and seals tightly, but adds a small amount of weight and creates a potential failure point if the zipper snags or breaks in the field. Some designs use a half-zip on one side only, which saves weight while still allowing easy entry.
Bottom-entry nets have an opening along the underside with a drawstring or elastic cord that cinches closed once you’re inside. They’re simple, light, and have fewer parts that can break. The learning curve is slightly steeper since you climb in from below, but many experienced hammock campers prefer them for their reliability.
The “Fronkey” style is a minimalist approach popular in warm climates like Florida. The net simply drapes over the ridgeline and hangs open at the bottom, attaching only at the ends of the hammock. There’s no zipper, no drawstring, and no shock cord. Despite the open bottom, the drape of the fabric is enough to keep mosquitoes out even for restless sleepers. It’s the lightest option and the easiest to get in and out of.
Sizing and Ridgeline Setup
A net that’s too short bunches up and presses against your face. One that’s too long sags into a floppy mess that collapses onto you when you shift positions. Most standalone nets are designed for hammocks up to 11 feet long, with a typical net length around 10 feet and a width around 50 inches.
The key to keeping the mesh off your body is a structural ridgeline, a taut cord that runs above the hammock from one end to the other. The standard formula is to set the ridgeline at 83% of the hammock’s laid-flat length. So an 11-foot hammock gets roughly a 9-foot, 1-inch ridgeline. The net drapes over this line, which holds it up like a tent pole and creates clearance between the mesh and your face.
For standalone nets, the ridgeline typically runs outside the netting, passing through elastic loops at each end of the net. Shock cord tied to the corner loops of the mesh pulls it taut, creating a roomy enclosure that stays tensioned whether or not you’re in the hammock. This self-tensioning setup means the net won’t collapse when you roll over or sit up during the night.
Protecting Against Bites From Below
Here’s something many first-time hammock campers miss: mosquitoes can bite through the bottom of your hammock. A persistent mosquito can penetrate almost any single layer of woven fabric, even heavy denim, by probing its proboscis through the gaps between threads. Your body weight compresses the hammock fabric against your skin, making it even easier for them to reach you.
A top-only mosquito net does nothing to solve this problem. You have several options for underside protection:
- Sleeping pad or bag: Placing a sleeping pad, sleeping bag, or extra layer of fabric inside the hammock creates enough thickness that mosquitoes can’t bite through.
- Double-bottom hammock: Some hammocks are built with two layers of tightly woven nylon on the bottom. They weigh more but are completely mosquito-proof from below without any additional gear.
- Underquilt: If you’re using an underquilt for insulation (which hangs beneath the hammock), it also serves as an effective physical barrier against bites.
- Permethrin on the hammock bottom: Spraying the exterior of the hammock fabric with permethrin kills or repels mosquitoes on contact. This is a common practice in tropical regions for hammock campers who want to keep their setup lightweight.
Permethrin Treatment for Extra Protection
Permethrin is an insecticide that kills mosquitoes, ticks, and other insects on contact with treated fabric. Unlike topical repellents you apply to skin, permethrin bonds to fabric fibers and lasts through weeks of use, rain exposure, and multiple washes. It’s odorless to humans once dry and won’t damage nylon or polyester.
You can buy pre-treated nets or apply permethrin yourself using spray-on products. Treating both the mosquito net and the hammock’s outer fabric creates a dual barrier. One application typically provides protection for several weeks to months, depending on conditions. Reapply when you start noticing insects landing on the fabric without being repelled.
Permethrin is most useful as a backup layer rather than a replacement for physical mesh. A fine-mesh net keeps insects out mechanically, while permethrin handles the ones that land on the netting or probe the hammock bottom. Together, they cover the gaps that either approach alone would leave.
Choosing Based on Where You Camp
Your destination determines how much protection you actually need. For weekend trips in temperate forests during peak mosquito season, a standalone net with standard 156-to-200-hole mesh and a sleeping pad underneath handles the job. The setup is simple, affordable, and packs down small.
For backcountry trips in heavily wooded or swampy areas, an integrated bug net hammock eliminates setup mistakes and ensures complete coverage. Pair it with an underquilt or pad for bottom protection.
For tropical, coastal, or subtropical environments where no-see-ums and sandflies are present, you need mesh in the 1,000-to-2,000 range, a double-bottom hammock or underquilt, and permethrin treatment on exposed fabric. Anything less and you’ll spend the night being bitten by insects small enough to walk through standard netting.
